This paper explored the possibility of improving the pronunciation of English as a Foreign Language (EFL) learners by correcting their mouth-lip movement through visual feedback methods. As an EFL learner, I noticed that while learning pronunciation, for some words, the mouth-lip movement (e.g., opening size and duration) will affect the final pronunciation.
